Abstract In order to evaluate energy consumption of the light and small unit sprinkler system objectively，the calculating methods and evaluation indicator of unit sprinkler system were deduced based on the hydraulic machinery energy basic approach and unit sprinkler system structure and operating characteristics. By borrowing ideas of hydraulic computating methods of pipeline with multiple outlets, the hydraulic procedure and methods for unit sprinkler system pipeline were put forward by using back step method to handle the hydraulic calculation of pipeline and applying iteration method to solve the flow and head of sprinkler. Example analysis shows that the calculating and evaluating methods have the advantages of simple to use, easy to calculation, comparability, maneuverability, reliability and meeting practice projects. The calculating and evaluating methods will provide the theory basis for reasonable selection of pump，optimizing configuration and design of pipe installation and product development of unit sprinkler system, and have important theoretical significance and practical value for improving efficiency and reducing energy consumption of unit sprinkler system installation.
